Your community is exactly what I have been looking for.
Yes the Tristar is configured for 12 volts. My enclosure is 9x9x18 inches and I have 5x6x8 inches for all the electronics. Are these surge protectors overkill? I can use one line for the computer and the other for the camera. Wish I could find something open chassis and cheaper. Have not thought about battery backup.
Thank you for your expertise,
